LCC warns Transport for London that 'early start' is dangerous to cycling at large junctions
The London Cycling Campaign has written to Transport for London warning it not to replicate the 'early start' facility that has been installed at the eastbound entrance to Bow roundabout at similar large junctions.
At present, TfL is ignoring the views of local cyclists and ourselves with plans to install the same facility on the westbound side of the roundabout and at other unsuitable sites in the capital.
Our letter to TfL points out that 'early start' facilities would only be able to create enough time for cyclists to get out of the path of left-turning vehicles at small junctions.
The problems of the design are:
- Significant left-hook risk to cyclists
- Poor understanding by all road users
- No crossing facilities of any kind for walkers
- Cyclists have long red phase, compared with motorists
Despite the new layout at Bow, it's still possible for cyclists to be put in the same circumstances that caused the death of Brian Dorling last year: cycling across the exit of the roundabout with motor traffic turning across their path.
We warned TfL that its chosen system presents cyclists with significant risk and that better systems exist to eliminate that risk.
We've noted considerable slack in the signal timing at Bow, which is sufficient to allow a completely separate cycle phase, a solution that would also benefit pedestrians (who already often use this ‘dead time’ to cross - see below).
The 'early start' system at Bow is not helped by the widespread confusion among drivers and cyclists as to how it should work.
The changes at Bow roundabout came about after campaigning from LCC in the wake of two deaths in three weeks in 2011.
